Abstract
AIM: To discuss the relationship between the degree and type of ametropia and amblyopia in children.
METHODS: Thirty-six cases (72 eyes) with the age ranging from 3 to 12 years whose uncorrected visual acuity could not be rectified to 0.8 were from the out-patients. They underwent atropine mydriasis, computer objective examination, and the retinoscope subjective test.
RESULTS: The incidence of amblyopia was 55% in hyperopia, 25% in myopia and 83% in mixed astigmatism. The results showed that the incidence of hyperopia amblyopia was much higher than that of myopia amblyopia.
CONCLUSION: Myopia, hyperopia and mixed astigmatism are the main reasons leading to amblyopia in children. The ametropia degree is directly related to the amblyopia. The bigger the ametropia degree is, the more serious the visual impairment.

摘要
目的：探讨儿童弱视与屈光不正度数及类型的关系。
方法：门诊3～12岁36例72只裸眼视力不能矫正到0.8的儿童，采用阿托品散瞳、电脑客观检查法、联合检影主观检查法验光。
结果：远视性弱视的发生率为55%、近视性弱视发生率为25%，混合散光性弱视的发生率为83%。远视性弱视的发生要远远大于近视性弱视的发生。
结论：近视、远视、混合散光是造成儿童弱视的重要原因，且屈光不正度数越大越易发生弱视，对视力损害越严重。
